India's energy landscape is undergoing a transformation with the recent commissioning of the 500 MWe Prototype Fast Breeder Reactor (PFBR) in Kalpakkam, which has achieved criticality. This landmark event not only advances India's nuclear capabilities but also supports its ambitions to become a global data center powerhouse. The Indian government has initiated plans to increase nuclear capacity to 22.38 GW over the next six years, fostering private sector involvement in nuclear energy generation. Industry leaders highlight that stable, clean, and reliable nuclear power could serve as a 'geopolitical moat' for India, especially as global demand for AI compute infrastructure rises. Experts note that while nuclear energy will play a crucial role, its significant impact on data center energy demands will likely be felt only after 2032, with large-scale developments expected by 2040. The integration of nuclear energy into India's data infrastructure requires immediate policy frameworks and regulatory reforms to support its long-term viability and cost-effectiveness. As the demand for energy from data centers surges, driven by advancements in artificial intelligence, nuclear energy is being reconsidered as a viable solution for sustainable and reliable power.
